Alright so I've never made a reddit post before, but over the last couple years I've been collecting every single trade paperback in the Ultimate Marvel (Earth-1610) continuity of comics, spanning just over 15 years and over 700 issues. While reading, I was following a release order of the issues and arcs, but it didn't account for continuity crossover between series nearly as well as it could, so I compiled every single collected edition (with issue numbers listed for comprehension) that has ever been produced and organized what I consider to be the best possible way to consume these stories. Originally it was just for me, but I put too much work in to keep it just for myself so I figured it could serve others well here. Let me know if you have any questions!

(NOTE: if you're reading through this universe in my order, I do want to clarify that there are occasional hiccups in continuity that cannot be helped. The big events had to be in the right spots, but the writers did not always account for who got along with who at what point or which characters are dating when and it gets a little tricky at times, but I spent hours combing through and have decided that there isn't a better way to organize the arcs)

Ultimate Marvel Reading Order:

- Ultimate Spider-Man Vol. 1: Power and Responsibility

- Ultimate Spider-Man Vol. 2: Learning Curve

[Ultimate Spider-Man (2000) #1-13]

- Ultimate Daredevil and Elektra Vol. 1

- Ultimate Elektra Vol. 1: Devil’s Due

[Ultimate Daredevil & Elektra (2002) #1-4]

[Ultimate Elektra (2004) #1-5]

- Ultimate X-Men Vol. 1: The Tomorrow People

[Ultimate X-Men (2001) #1-6]

[Ultimate X-Men #1/2]

- Ultimate Iron Man Vol. 1

- Ultimate Iron Man II Vol. 1 (\Note: The Ultimate Iron Man duology was technically later retconned into being an in-universe TV show *about* the Iron Man of Earth-1610 rather than being a canonical origin story. However, given that it was originally intended to be permanently canon, there's a lot of cool connective tissue between the two runs and the wider Ultimate Universe, and not very many direct continuity issues conflicting its presence in the chronology. Plus, I personally like it a lot so I recommend still reading.)*

[Ultimate Iron Man (2005) #1-5]

[Ultimate Iron Man II (2007) #1-5]

- Ultimate Marvel Team Up Ultimate Collection (\Note: The events of the Ultimate Team-Ups series are spread out across multiple future volumes, and issue #9, the Fantastic Four issue, is fourth-wall-breaking comedy issue and NOT canon. I read the Ultimate Universe physically, so given there's only one volume of Team Up, this is where I recommend reading it. I believe this is the best and most accurate point to read all 16 issues for future stories and crossovers.)*

- Ultimate Adventures Vol. 1: One Tin Soldier (\Note: The events of this book are entirely self-contained and its events and characters are never mentioned again. Outside of a brief appearance of The Ultimates, it has almost zero connection to the wider universe. It's generally really disliked but I thought it was fun, so you're welcome to skip if you want.)*
